# Founding Engineer

e2e is the open source verification layer for the agentic coding era. You describe what should work in plain English, and e2e checks it like a real user would, on web, iOS and Android. 1.5M npm downloads and 12k GitHub stars in the first month. We're a small team in San Francisco and Warsaw, backed by YC, Credo, Point Nine and Script Capital, and the co-founders of Uber, Snowflake and Vercel. $9M+ raised. You'll own the core: the agent, the web and mobile engines, and the cache that makes runs fast and cheap. You'll ship it, measure it, and fix it when it breaks. You're a fit if you: write great TypeScript and have run things in production have shipped LLM features with tool calling own what you build, end to end Bonus: browser automation, iOS/Android internals, or open-source projects people rely on. We look at your GitHub first. Interview process: Intro call with a founder (30 min) Technical deep dive on your GitHub and past work Paid work trial with the team, if your situation allows it (optional)
